The Strait of Malacca is a narrow stretch of water 800km long between the Malay Peninsula to the northeast and Sumatra to the southwest, connecting the Indian Ocean and the Pacific Ocean. It is one of the busiest and most important trade and strategic routes in the world. The strait was named after the Malacca Sultanate that ruled over it between 1400 and 1511. Over 120,000 ships now pass through the Strait every year, creating a billion-dollar highway for transporting goods such as oil, gas, and manufactured products. This trade route accounts for a third of the world's trade and 50% of its oil shipments. Participants will spend the day relaxing before the circumnavigation is completed, and the journey arrives back in Singapore the next morning.
